OBJECTIVETo investigate the method and indications for reconstruction of facial complicated soft tissue defects with free flaps by microsurgery.

METHODS37 patients (16 males and 21 females, aged from 1 to 54 years) with different size of facial soft tissue defects were reconstructed with free flaps, including 10 latissimus dorsi myocutaneous flaps, 3 thoracodorsal artery perforator flaps, 9 scapular flaps, forearm flaps and 9 postauricular flaps. The defects size ranged from 1 cm x 2 cm to 25 cm x 12 cm.

RESULTSVenous obstruction happened in 3 postauricular flaps, resulting partial necrosis in 2 flaps. All the other flaps survived completely. The cosmetic and functional results were both satisfactory.

CONCLUSIONSThe facial complicated soft tissue defects can be treated successfully with free flaps by microsurgery. The wounds can be healed primarily with short recovery time and reliable cosmetic and functional result.

Objective:To discuss clinical effect of addition and subtraction therapy of Ditantang combined with Taohong Siwutang to cerebral infarction and syndrome of phlegm and blood stasis blocking collaterals during early recovery， and to study protection to brain nerve. Method:One hundred and fifty-two patients were randomly divided into control group （76 cases） and observation group （76 cases） by random number table， 71 patients in control group completed the therapy （5 patients were falling off， missing visit or eliminated）， and 70 patients in observation group completed the therapy. Both groups' patients got comprehensive rehabilitation measures. Patients in control group got Zhongfeng Huichun pills， 1.5 g/time， 3 times/day. Patients in observation group got addition and subtraction therapy of Ditantang combined with Taohong Siwutang in the morning and at night， 1 dose/day. The treatment was continued for 12 weeks. Before and after treatment， scores of degree of neurological deficit， Barthel （BI） index， Fugl-Meyer scale （FMA）， modified Rankin scale （MRS） and syndrome of phlegm and blood stasis blocking collaterals were graded. And levels of malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， superoxide dismutase （SOD）， advanced oxidation protein products （AOPP）， vascular endothelial growth factor （VEGF）， brain-derived neurotrophic factor （BDNF） and neuron specific enolase （NSE）. And cerebral hemodynamics were detected， and peak flow velocity （VS）， vascular resistance index （RI）， pulsatility index （PI） and cerebrovascular reserve function （CVR） were recorded. Safety was evaluated. Result:After the 6^th week and 12^th week of treatment， scores of degree of neurological deficit， BI， FMA， MRS， syndrome of phlegm and blood stasis blocking collaterals， AOPP， MDA， NSE， RI and PI were lower than those in control group （P<0.01）， levels of SOD， GSH-Px， BDNF， VEGF， Vs and CVR were higher than those in control group （P<0.01）. The clinical effect was better than which in control group （Z=2.109， P<0.05）. Besides， there was no adverse reaction caused by Ditantang combined with Taohong Siwutang. Conclusion:Ditantang combined with Taohong Siwutang can ameliarate the hemodynamics， reduce the lipid peroxidation damage， regulate the neurovascular repair factor， so it can promote the repair of nerve tissue and function， clinically reduce the degree of nerve function defect， improve the ability of daily life and exercise when it used to cerebral infarction and syndrome of phlegm and blood stasis blocking collaterals during early recovery， and it is good for clinical effect and safe using.
